Mariano's upscale supermarket chain plans to open a store in Naperville, a company spokesman said Friday.

"We have a signed lease with the landlord of the Fox Run Square shopping center at 1212 S. Naper Blvd. … and we are moving through the municipal approval process," James J. Hyland, vice president of investor relations, corporate communications and public affairs for Mariano's owner Roundy's Supermarkets Inc. said via e-mail.

He declined further comment.

Since 2010, Mariano's has opened more than two dozen stores in the Chicagoland area and officials have said more are on the way. The Naperville location will be in a shopping center at Naper Boulevard and 75th Street that once housed a Dominick's store and is across the street from a Jewel.
